Toall 'whomi'it may concern:

god

Be it known that I, JOSEPH A. MCGEE, a citizen of the United States, residing at Big Sprin inthe county of vBoone land State of In( iana, have invented certain new and useful Im rovements in Multi `le-Disk Friction-Clutc es, of which the ollowing 'is a specification. y

This invention relates. to improvements in a coupling which comprises in its construction a plurality of disks that are brought together with Va `regulated pressure to producerictional contact.

The invention may be used on a variety of machines and is especiallyapplicable to au.

tomobile .construct1on.

The object of the invention is to rovide a simple, durable, and easily operate means .l

for applying regulatedressure to friction isks of a couplin of t 1e above character,

whichmeans may e capable of producing great frictional pressure and holding 4ig. 2 is a like section showing the sliding.

sleeve, and arms pivotally connected therewith, in positions to render the couplings operative; Fig. 3 is. a section on the line 3-3 of Fig. 2; Fig. 4 is a section on the line 4 4 of Fig. 2; Fig. 5 is a s ection on the-line 5-5 of Fig. 1 and Fig. 6 is a section on the Like characters of reference indicate like arts throughout theseveral views of the ralwings.

1 is ashaft upon which the coupling is mounted Aand which is driven by means of any suitable power. (Not shown.) Mounted loosely upon the shaft 1 is a sleeve 2.'

which is angular in cross-section on its outer sides and is limited inits' end-movement by lcollar 2 on shaft 1. Also mounted upon the sleeve 2 in close contact with each other and rotating'with said sleeve are four hubs, each r having a circular disk 4.,

5 is a cylindrical shellhaving a head 6,

here show nas an integral part ofthe shell,

contact when required, but will also be capable` at one end, said end having a central bore to receive a hub of one of the disks et. All of the disks 4 are mounted within the shell 5- in the manner shown in Fig. l. The hubs of the disks 4 all extend in the saine direction from their respective disks-and loosely mounted on veach hub except the outer one upon which the head 6 is mounted, is a disk 7. Each disk 7 has a pairof diametrically opposite peripheral lugs 10.

shown at 9, to receive `said peripheral lugs 10 of the disks 7'to compel the disks 7 to rotate with the cylinder.

A head l2 is mounted upon the shaft 1 and is secured thereto in a fixed .m'anner, here shown as by meant'A of the set screw 13. This head 1-2 is also provided with peripheral lugs 10 which enter the grooves 9 of the cylinder 5 to compel a corresponding rotary movementof said cylinder andh'ead.

A sleeve 14 isslidingly mounted upon the shaft 1 and is movable 'longitudinally ofthe shaft by means of a lever 15. The lower end ofthe lever 15 -is bifurcated tojstraddle thesleeve 14 as shown .in Eig. 3, and' is piv- 4otally attached to trunnions 2l of the s lit ring 22. The split ring 22 is mounte in an annular groove in the sliding sleeve 14. The lever 15 .is swingingly mounted on a fixed pivot 23. The inner end. of the sleeve 14 is diametrically notched to receive the ends of the stems of a pair of T-shaped lovers 16 which are pivotally secured at their stem ends to the sleeve 14, in said notches. 'lfhe outer ends of the 'levers 16 have the cross-arms, at the ends of which therollers' 17 and 18 are respectively mounted. The rollers 17 bear against the follower-head 12,

The cylin- A drical shell 5 isl longitudinally grooved as and the rollers 18 bearagainstthe flangesor blocks 20 secured opposite each-lever 16 to -the inner lwall of the cylindrical shell 5'. YVhen the sleeve 14 is moved inwardly of the 'cylindrical shell 5 by being slid longitudinally on shaft 1 by the operation of the lever 15, the T-shaped arms 16 approach the positions at right angles to the s aft 1, as shown in Fig. 2, ther-eb causing the roller 17 to press against the follower-head 12 and move the cylinder longitudinall of the shaft thereby impinging the disks7 between the disks 4, with more or less force, depending upon the position of the levers 16, thereby causing the sleeve on which the disks are mounted, to be coupled as above described. .The pulley 3, which is mounted on sleeve 2,

will thereby be correspondingly coupled to the shaft 1.. By regulating the pressure and. friction between the disks, by means of lever 15, the pulley 3 may be permitted to sli by the slipping of the disks, or it may lie held against slipping by the exeroise of sufficient force applied through said lever 1 5. The inclosure of the cylinder is filled with oil around the disks to thoroughly lubricate the parts and prevent hea-ting.

Having thus fully described my invention, what I elaim is new and wish to secure by Letters Patent of the United States, isz- 1. In a clutch, a shaft, a sleeve loosely mounted on the shaft, disks mounted upon and rotatin r with the sleeve and adjustable longitudina y thereof, a cylindrical shell surrounding said disk having inside longitudinal grooves, a cylinder-head at one end and inwardly projecting flanges at the other end of said cylindrical shell, other disks between said first disks said last disks having peripheral lugs entering the grooves of the cylindrical shell, a fixed head mounted ina fixed manner on the shaft between which -and said eylflinder-head all of said disks are impnged y a longitudinal movement of said cylindrical shell, asleeve lslidingly mounted on the shaft, T-shaped levers havin their stems pivoted to the sleeve .and an of each of the cross-arms thereof bearf ing against the fixed head and the other end against said inwardly projecting [langes of,

the cylindrical shell.

2. In a clutch, a shaft, a sleeve loosely mounted on the shaft', disks mounted upon and rotating with the sleeve and adjustable longitudinally thereof, a cylindrical shell surrounding said disk having inside longitudinal grooves, a cylinder-head at" one end and inwardly projecting flanges at the other end of said cylindrical shell, other disks between said irst disks said last disks having peripheral lugs entering the grooves of the cylindrical shell, a fixed head mounted in a fixed manner on the shaft between which and said cylinder-head all of said disks are impinged by a' longitudinal movement of said cylindrical shell, a. sleeve slidingly mounted on the shaft, T-shaped levers having their stems pivoted to the sleeve and an end of each of the cross-arms thereof bearing against the fixed head and the other end against said inwardlyl projecting llanges of the cylindrical shell, and friction rollers 'mounted in the ends of said cross-arms.

In witness whereof, I have hereunto set my hand and seal. al'. Indianapolis, Indiana, this 12 day of April, A. l). one thousand nine hundred and ten.
